Benefits of technology

The patent describes a transport refrigeration system that uses natural gas and a turbine to power an electric generator. The system includes an artificial aspiration device that uses compressed natural gas and compressed air to power the engine. The system also includes a charge air intercooler jacket and a transfer tube to cool the hot compressed air. The technical effect of this system is to improve engine performance and fuel efficiency by utilizing the power of the turbine to generate electricity and cool the hot compressed air.

Problems solved by technology

The natural gas is typically decompressed through a series of regulators but this decompression process is inefficient.

Embodiment Construction

[0020]Referring to FIG. 1, a transport refrigeration system 20 includes a refrigeration unit 22, an electric generation device 24, a natural gas engine 26 for driving the electric generation device 24, and a controller 30. The refrigeration unit 22 functions, under the control of the controller 30, to establish and regulate a desired product storage temperature within a refrigerated cargo space wherein a perishable product is stored during transport and to maintain the product storage temperature within a specified temperature range. The refrigerated cargo space may be the cargo box of a trailer, a truck, a seaboard shipping container or an intermodal container wherein perishable cargo, such as, for example, produce, meat, poultry, fish, dairy products, cut flowers, and other fresh or frozen perishable products, is stowed for transport.

[0021]The transport refrigeration unit 22 includes a refrigerant compression device 32, a refrigerant heat rejection heat exchanger 34, an expansion ...
